AITA for being mad my sister doesn’t want to go to her birthday party after seeing her husband?

My little sister (F26) got married about 6 months ago and since then has been “bride” 24/7. Every conversation is about her wedding or her “bride body”. She has dropped all our friendships since meeting her husband, which we all think is a bit excessive. <br><br>We tried to suggest that she could ease up on the whole “bride” persona and go out to things together, but she has said no because husband doesn’t want her to. Last week she said she wanted a birthday party and wanted to do it the way she wants and invited a bunch of high-end restaurants. We suggested she do something at home or something in the park to save on costs but she said husband wants it to be at an expensive restaurant.<br><br>We were a bit surprised because she doesn’t really seem that into her husband and has complained about him before, but when it comes to throwing her a party she’s totally on board with doing whatever he wants.<br><br>Well, now that all the plans have been made, we’re all excited to celebrate her birthday with her. But today she called a meet and greet to talk about something and we all went, thinking it was about a change of date or something small. <br><br>Turns out she wants to invite her husband to the party because he’s been “supporting her through the wedding planning” and “it’s her day but she wants him there”. We all thought this was a bit odd and asked why he’s been at all the wedding planning meetings, photoshoots, and bridal showers if he hasn’t been invited? She said he’s “bride’s best man” and can’t wait around all day for her to get her hair and make-up done. We asked why not then can’t he wait for the party? <br><br>We also asked if she’s really that close with him to invite him to her birthday? She said she wants him there and is mad we’re questioning this. I asked if she wants to invite him and have him order the most expensive thing on the menu with an open bar and dance till dawn? She said no and got mad at me.<br><br>Now I’m just confused. Why invite her husband if she’s not really that into him? If she’s really close with him why hasn’t she mentioned him in all this time? If she’s not close with him why invite him now? If she doesn’t want to invite him why are we having a party in the first place? <br><br>Everyone is just mad at her because she’s been “bride” non-stop and now wants to invite her husband to the party? I’m just so confused and honestly done with her whole situation.<br><br>So AITA for being mad about her wanting to invite her husband?
